Quirinal Palace in Rome

You're standing at the Quirinal Palace, on top of the Quirinal, the highest of Rome's seven hills. This vast palace is the official residence of the President of Italy. First, take a look at the square in front of you. The fountain with two giants each taming a horse shows Castor and Pollux. They're a reminder of the Roman baths that once stood here, in the days of Emperor Constantine.
